Review Meta Analysis
Safety and efficacy of dabigatran versus warfarin in patients undergoing catheter ablation of atrial fibrillation: a systematic review and meta-analysis.
Dabigatran etexilate, a new thrombin inhibitor, has been shown to be comparable to warfarin in patients with atrial fibrillation (AF). However, there is a limited body of evidence on the efficacy and safety of using dabigatran among patients undergoing AF catheter ablation. ⋯ In the specific setting of AF catheter ablation, this first pooled analysis suggests that patients treated with dabigatran have a similar incidence of thromboembolic events and major bleeding compared to warfarin, with low event rates overall.

Randomized Controlled Trial
Effects of intravenous and oral β-blockade in persistent asthmatics controlled on inhaled corticosteroids.
Despite their benefits in the treatment of cardiovascular disease, β-blockers are seldom used to treat asthmatics. We assessed the safety and tolerability of acute dosing with esmolol and propranolol in patients with asthma. ⋯ Intravenous esmolol was administered without any adverse effects on pulmonary function in selected, stable, mild-to-moderate asthmatics controlled on inhaled corticosteroids. Tiotropium prevented propranolol induced bronchoconstriction after acute dosing during up-titration to 80 mg with no adverse impact on asthma control.

Comparative Study
Retrospective analysis of the effect of angiotensin II receptor blocker versus β-blocker on aortic root growth in paediatric patients with Marfan syndrome.
Cardiovascular pathology, including aortic root dilation at the level of sinus of Valsalva (SV), is one of the major causes of morbidity in paediatric patients with Marfan syndrome (MFS). β-Blocker (BB) is well established to slow aortic dilation in MFS. Less is known about the effectiveness of angiotensin II receptor blocker (ARB) on aortic dilation in paediatric patients with MFS. ⋯ Both concepts lead to a significant reduction of SV dilation. The effect of ARB and BB is similar. This is the first study concerning the comparison of ARB and BB in previously untreated paediatric patients with MFS. The results of the study show that both treatment strategies are beneficial in paediatric and adolescent patients.
